This fascinating book contains photographs and script describing the processes used by the enormous Larkin Factory to manufacture a large number of household products in 1918. The Factory's then-innovative machines' function is described step by step, and are a marvel of efficiency. The Staff's handiwork is also explained; as are the ingredients used in their products . The photographs in the book are marvelous. Learning which products the households of 1918 used is very interesting. This little book kept me entertained as I flipped through its pages. I highly recommend it.
